Emergency Calls
This mobile device, like any wireless mobile device, operates using
radio signals, wireless and landline networks, as well as
user-programmed functions, which cannot guarantee connection in
all conditions, areas, or circumstances.
Therefore, you should never rely solely on any wireless mobile
device for essential communications (medical emergencies, for
example). Before traveling in remote or underdeveloped areas, plan
an alternate method of contacting emergency services personnel.
Remember, to make or receive any calls, the mobile device must be
switched on and in a service area with adequate signal strength.
Emergency calls may not be possible on all wireless mobile device
networks or when certain network services and/or mobile device
features are in use. Check with local service providers.
